ANALYSIS OF SMOKE STRATIFICATION AND SMOKE LAYER THICKNESS IN UNDERGROUND CAR PARKS

ABSTRACT
Fire accidents in underground car parks have a significant impact on the building structure and lives of people and firefighters. Different methods are used to obtain a reliable estimation of fire and hot smoke influence on the building structure. Numerical modelling is crucial in the fire design and is a useful tool to determine smoke stratification and clear layers for safe human evacuation and firefighter access. Smoke stratification can be checked separately for any time interval in any section of an underground car park, regardless of the underground car park architecture complexity. This paper describes numerical modelling of smoke stratification and movement in an underground car park. The results show smoke movement and smoke layer thickness during the evacuation time, and how they can help reduce the harmful influence of fire on the underground car park structure.
